would it be likely we see all businesses have their own coin? Amazoncoin? Walmartcoin? (i use these since these are internationally most known. Not an American..)
This makes every company look into cryptocurrencies and make them think that they have their own token or coin just for using it to their own service.
But I haven't seen some companies that are successfully using their own token creation because they are still depending to fiat / dollars and if there is a coin that they are accepting it's only bitcoin.
Amazon's acceptance of bitcoin is just a rumor and I don't even think that they will be helding their own coin just for their own advantage. They see cryptos as something that is really volatile and decentralized.
It is better to use other more famous currency because of this reason. No one else would support and maybe they would start making their own promos and token hunters would just be the making profits rather than a company it self.
